razors, whether of the safety razor type or blades attached to handles, and an object of my invention, among others, is to pro vide a razor stropper exceedingly simple in construction and effective in operation.

A razor stropper embodying my invention and in the construction and use of which the object above set out, as Well as others, may be attaihed is illustrated in the accompanying drawing, in which- Figure 1 is a View in side elevation. of a razor stropper embodying my invention, the strop being removed and parts broken away to show construction. Fig. 2 isa detail view in section through the device.

In the accompanying drawings the numeral 5 denotes end pieces of a frame that are spaced apart and rigidly held by a supporting stay rod 6, upper stay rods 7, and lower stay and guide rods 8 and 9, the guide rods 9 supporting guide rollers 10. These stay rods are secured'to the end pieces in any suitable manner to rigidly hold the end pieces in fixed relation. A ring 11 is secured to the supporting stayrod 6 as means for attachment of the device to a fixed object for use.

An actuating roll 12 in the end pieces and is provided with an actuating cam 13, in the form herein shown this cam being in the form of a screwi thread, the grooves of which terminate in stop shoulders 14. A. runner support 15 is secured at each end to the end pieces 5, and a runner '16 is mounted for reciproeat ing movementlengthwise upon said runner support, said runner having a'lug l'l extending'into the groove of the thread or cam 13,. I

A blade holder 18 is rigidly secured to the runner, and spring arms 19 press with their free endsonthe op osite sides 0% the holder to hold' it normally-in a position intermediate the extremi'tiesof its lateral movement to be hereinafter described. spring arms may. be secured; to any fixed Specification of Letters Patent.

The blade holder 18 is composed of a base 21 and, resilient side parts resting against each other attheir outer or free ends, said resiliency being such-that the edge of a razorblade may be forced. between the side parts so as is project a slight distance below their free The arbors 23 of the actuating roll 12 are located in slots 24 in the end pieces, and a strop 25 is passed over the actuating roll and along the opposite sides thereof between'the stay rods 8 and rollers 10, the ends of the shop projecting-sufficiently to enable them to be grasped by the hands of the operator for the purpose of stropping the blade.

While I have shown the invention as embodied herein in a preferred form of construction, this may be departed from to a greater or lesser degree Without departing from the spirit or intent of the invention.

I claim 1. A frame, an actuating roll supported in the frame and having an actuating cam, a runner mounted between the ends of the frame and in engagement with the cam to be reciproeated thereby, a blade holder secured to the runner, and strep extendin over the actuating roll and having its end s prothe frame and having an actuating thread constituting a cam, said thread terminating in a stop shoulder, a runner having a lug pro eet1ng into the groove in said thread,

blade holder secured to the runner, and a ting roll supported in essee:

strep passed over the actuatin roll and haw ing its ends projecting beyond the frame.

4:. frame having slots therein, an actuating roll journaled in said slots, said roll having an actuating cam, a runner in engagen'ient with the cam, to he reeiprocated thereby, a blade holder secured to the runner, and a strep passed over the actuating roll and having its ends projecting bey nd the frame. i

5. A frame, an actuating roll supported in the frame and having an actuating earn, a runner in engagement with the cam to he reciprocated thereby, a blade holder secured to the runner, means for yieldingly retaining the holder normally in a mid position, and a strop passed over the actuating roll and having its ends projecting beyond the frame.-

ating rollsupported between the end pieces and having cam, a runner supported "between said. end pieces upon a runner support mounted in said end piecazs and in engagement with said cam, and a blade holder secured to the runner, said actuating roll be ing ar 'anged to receive a strep by means of which the roll is rotated.
